In this work we show how to retrieve information about temporal changes of turbulence in the atmosphere based on in situ wind velocity measurements performed by aircraft. We focus on the stratocumulus-topped boundary layer high-resolution data taken

We compare turbulence properties in coupled and decoupled marine stratocumulus-topped boundary layers (STBLs) using high-resolution in situ measurements performed by the helicopter-borne Airborne Cloud Turbulence Observation System (ACTOS) platform i

Wide-spread presence, persistence and high albedo of marine stratocumulus clouds makes them important for the energy balance of the planet, hence also in model-based climate predictions. Typically, stratocumulus clouds occupy upper few hundred meters
